Description
Summary:The sea surface wind (U10) is one of the vital variables needed to monitor the tropical cyclone development stages. Since the previous operational altimeter U10 product despair significantly inside extreme tropical cyclone conditions, the least attention is given to understand the tropical cyclone. With the latest improvement of high U10 accuracy estimates inside the tropical cyclone environment developed for altimeter satellite, tropical cyclone wind characterizations can be anticipated. This study aims to derive prominent tropical cyclone wind characteristics namely the centre and the radial extends threshold used by the agency in describing the tropical cyclone. The results demonstrated that the objectively derived characteristics from the Jason-3 altimeter for Typhoon Jebi 2018 were in good agreement with the best-track reported. This study draws new perspective of instantaneous observation for tropical cyclones characterisation from the altimeter satellite which can be vital complement of operational analysis.
